IMPROVEMENT lN GATES.

Specification forming part of Letters Patent No. 129,733, dated July 23, 1872.

To all whom it may concern:

Beit known that I, GEORGE HUNGERFORD, of Union, in the county yof McHenryand State of Illinois, have invented certain new and useful Improvements in Gates and do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of l reference marked thereon.

My invention relates to that class of gates which are thrown upon their` ends tobe opened; and it consists, first, in the devices for balancing the gate; and, second, in the devices for operating the gate to open and close the same, aswill be hereinafter more fully set forth.

In order to enable others skilled in the art to whichmy invention appertains to make and y use the same, I will now proceed to describek its construction andoperation, referring to the annexed drawing, which forms a part of this j specification, and in which- Figure l is a side view, showing the gate y closed, with 'dotted lines representing the saine open; and Fig. 2 is an end view of the same.

L represents a gate constructed in any suitable manner, and pivoted at its inner lower `corner between two posts, F F, which are braced by in lined braces `B B. The gate swings up an down on its pivot y between the` posts F F The outer end of the gate is provided with spring-latch, T, which springs to its place u1 der a cap on the post A when the gate drops to its placein closing, said post A being located on the other side of the road or carriage-way. To the gate L is secured an inclined 1ever,H, projecting inward and upward from the inner upper corner of the gate.

y This leveris jointed at J, and the outer hinged part is provided with an adjustable weight, I, which may be moved lto any point on the lever, as lthe weight of the gate may require. Upon each side of the gate, at the inner end,

is an upright post, G, to which the post F is connected, as shown inr Fig. 2. From each of these posts O, at a suitable height, extends an inclined arm, D, the'outer end of which is "forked, and in the same is pivoted a lever, E,

having at'its outer end a cord, U, with weight i WV hanging down. The inner ends -of the 1evers E E pass throu gh slots in their respective `posts G C, and have chains N N attached to them. These two' chains or ropes are attached to another rope or chain, S, one end of which, by a rod, P, connects with the lever H at or immediately below the joint J. The other end of the chain or rope S is attached to an angular plate, K, which is pivoted -in the upper end of an iron pin, a, fastened in the top bar of the gate. The plate K is, by a rod or wire b, connected with the spring-latch T at theouter end of the gate.

VThis mode of constructing a gate admits of its being'easily opened and closed by a person on horseback or in a vehicle without moving from his seat, simply by giving a downward pull on the rope U on either side. If closed, the gate is thrown up with alittle momentum, and with the balancing power of the lever H and the weight I the gate rises or turns on its pivot until the outer end of a lever strikes a post, Gr,V located a suitable distance from the inner end of the gate, when, from its own weight, the gate falls fully open, the lever H breaking its joint at J, as shown by the dotted lines in Fig. 1. If the gate is open when the downward Vpull is made on the rope U the gate is thrown down and closed, the lever H and weight I serving as a balance as soon as required, causing the gate to drop easily to its place.

The wire b, connecting the plate K and latch T, should be made Vof proper length, so as to liberate the latch from its fastening in the post A before the gate is pulled up.

Having thusfully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The arrangement of the slotted posts C C, inclined forked arms D D, and levers4 E E, the levers pivoted in the arms and their inner ends .working in the slotted posts, all substantially as herein set forth.

2. The arrangement of the levers E E, chainsI or ropes N N and S, and the rod P, this rod being attached to the lever H at or near the ioint J, substantially as herein set forth.

,3. The combination of the spring-latch T, rod b, pivoted plate K, pin a, and chain S, all substantially as and for the purposes herein forth.
